Application filed January 17,1920. Serial No. 352,063.

To all whom it may concern Beit known that I, Josnrii H. Porn, a

citizen of the United States, and resident of Hamilton, in the county of Essex. and State-of Massachusetts, have inventejdcer: tain. Improvements in Hcel-Seat-Roughing Machines, of which the following descrip tion, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts inthe several figures. w

This invention relates to the manufacture of boots and shoes and is illustratedas em.

bodied in amachine especially designed for treating-the heel seats of outsoles. to facilitate the heel attaching operation.v

When cement is employed to hold a heel to'the heel seat of an outsole preliminary to securing them together by nails, the heel is liable to slip laterally before-the cementsets. This liability is lessened by roughed ing the sole. When a ro-ughening operation is attempted by a hand-operated tool itis almost impossible to limitthe rougheningto that portion of the sole which will be covered by the heel, and the same is true whena sole is held in. contact with-an exposed portion of an ordinary rotary abrader with no means for positively limit-.

ing movements ofthe sole relatively to such abrader; a

An .object of the present inventionis to provide an improved machine forscratching orroughening up a surface of a shoe part such as the tread -face of the heel end of a. sole over a definitely limited area, as the area of that portion of a sole which is to be "covered by the heel of the shoe. v

An important feature of theinvention comprises the combination with a rotary abrader. of means fordetermining the'prop-.

er'location of a sole relatively to; the abrader, said means definitely "prescribing the area and shape of the solesurface to be roughened.

In the exemplification, of the invention illustrated in the accompanying drawings the machine comprises-a rotary' abrad'er anda rocking gage member subst-a'ntially tangential to the periphery f the abrader, said gage having a heel-lift shaped opening to define the shape and size of the area of the sole surface to be roughened.

A further feature of the invention comprises a rocking gage of the characterre ferred to having means for? preventing it 'rron being rockedbeyond a predetermined I limit 1n either direction whereby the. action E Nrorrica of the abrader will not be extended onto.

the gage" itself beyond the "area of the heel seat of the sole;

p These and other features of the invention, i 7

including-'sfcertain details -of construction andcombinatio'ns of parts, will be described more fully in connection with the accompanyin drawings and pointed out an the,

appended claims. y

z Projecting 'flOIl'lillle frame or standard 12 is a bearing 1.8 (Figs. 1 and 4) for a stem 1 or stud 19 having an arm 20 WVlllCll' carries.

a stud bearing 21 for the end portion 22 of the rocking gage presently described. In

order to adjust the pivotal support 19 rela-f tively to the periphery of the abrader, the stem 21 is adapted. to be rotated in the'bear ing 18 and secured in the V desired. rotative position by a set screw 23. I i I Preferably asuitable, washer, 24. will be gage will rock on a center practicalli interposed between the head of the screw 25 which holds the gage on the pivotal sup- ;ort 21 and the side "faceot said pivotal support so that the gage as a whole may rock quite freely upon'the pivotally support 21.

Extending across the taceot' the abra-der from the end part 22, and preferably integral with said part 22, are two side bars 26 to which is secured a plate 2-7 having an opening approximatingthe shape of a heel lift. Coacting with the plate 27 are two thin supports 28, and adjustablyconnected to the side bars 26 are two beveled blocks 29 which are secured in position by screws 30 which pass throughslots inthe side bars 26, one of saidslots being shown at- 31 in Fig.1.

Extending from the end plate '22 of the gage are two lugs 32 in each of which is mounted a stop screw 33' which may be secured in adjusted position by a binding nut 34. The inner ends of the two stop screws as best shown in Fig. 5, are adapted to alternately contact with upper side portions of the arm 2-0 when the gage as a whole is rocked on the pivotal support 2-1.

In operation, a sole the heel seat portion of which is to be roughened, is inserted endw'ise against the beveled blocks 29 with marginal portions of the heel end of the sole resting upon'the plate 27 and the thin supports 28. Said supports 28 are preferably attached to or integral with the blocks By adjusting said blocks along the bars 26 toward the right or lei't in Fig. 3, the length of the opening in the gage can be varied so that more or less of the length or the area of the sole to be roughened can be pressed into contact with the revolving abrader 16. lVhile the sole is being held by the operator with the margin of the heel seat portion thereofsupported by the as described, a rocking movement is imparted to the sole and the gage to the limits prescribed by the stop screws 33, thereby shifting the portion of the sole which will be in contact with the abr-ader from one side to the other of the heel seatportion, the structure being such that it is impossible for any abrading action to be effected upon the marginal portions of the heel seat end of the sole such as shown in Fig. 6 in which the shaded area represents the area of the sole which has been so 'atched or roughened. I

When the stud 19 is secured by the set screw 23 so that the pivotal support 21 is located in the position shown in Fig. 2, the in line with the periphery of the abrader. -By rotatably adjusting said stem 19 the pivot 21 can be setiat a greater or less distance from a line which would intersect theperipherv of the abrader to accommodate the work being done according to whether heavy or direction asto mar the edge portions of the sole. At the same time, owing to thefact that thesole tits between the side bars 26, while bearing upon the plate 2'4 and the thin supports 28, said sole can not be shifted from its position in the gage by the operation of the abrade'r the periphery otwhich is sweeping across the sole from side to side thereof. lilaving described my invention, what I claim as newand desire to secure by Letters Patentot the United States is: I
